ABSTRACT:
A nuclear magnetic resonance measurement system is disclosed which includes, in combination, means for generating an applied main magnetic field, and an array of at least two radio frequency current loops. The loops are electrically connected in parallel, and are oriented in a generally planar relationship with respect to each other. The loops are connected in phase with respect to each other so that the component of magnetization generated by the loops which orthogonal to the direction of the applied main magnetic field is in the same general direction. A capacitor is preferably electrically connected in parallel with the loops.
